Each power supply connects to the power rail in the router. The power rail distributes the output power
produced by the power supplies to different router components. Each power supply provides power to
all the components in the router.
Each power supply has its own fan and is cooled by its own internal cooling system. Hot air exhausts from
the rear of the chassis.

JNP10K-PWR-AC2 Power Supply
The JNP10K-PWR-AC2 power supply is a high-capacity, high-line model that is designed to support either
AC or DC systems in either a low power or high power mode. The power supply takes AC input and
provides DC output of 12.3 VDC, 5000 W with a single feed and 5500 W with a dual feed. For AC systems,
the operating input voltage is 180 to 305 VAC and for DC systems, the operating input voltage is 190 to
410 VDC.
The number of power feeds and whether the power supplies provides high or low output power is configured
using a set of dip switches on the faceplate of the power supply. If any power supply in the chassis is set
to low power, all power supplies are also set to low power, regardless of their dip switch settings. This
design is to prevent overloading of the power supply that is set to low power. See Table 14 on page 64
for the settings for the dip switches.
